🔧 A135F (U11) – eMCP Repair / Change with EasyPlus
I had an A135F (Galaxy A13, UB – U11) on my desk last week with a bad eMCP. The customer said it wouldn’t reset and EFS wouldn’t mount. If you’ve been around Samsung repairs long enough, you know exactly the headache I’m talking about.
Here’s how I sorted it — simple steps, nothing fancy, and it worked first try.
📌 What This Fix Handles
Swapping a dead or faulty eMCP
EFS not mounting after repair
Factory reset failing
Works even with EUB closed
🛠 What You’ll Need
EasyPlus (Samsung) – I used the vendor version
BL & sec_efs package – already prepared
The correct PIT file for A135F (U11)
🔹 Steps I Took
Fired up EasyPlus on my PC.
Picked A135F (U11) from the list.
Loaded the PIT file — this bit is important, or things won’t map right.
Didn’t bother loading BL separately — no need, it’s included in the files.
Flashed BL + sec_efs. Let it finish without touching anything.
Rebooted and… EFS mounted perfectly.
💡 Why It Works
The BL gets the phone booting properly after the storage change. The sec_efs repairs the EFS area so the device can read its identity again. Doing it through EasyPlus keeps things stable and safe — I’ve had fewer issues compared to generic tools.
⚠ A Few Tips
Only for A135F (U11) — don’t try this on other A13 models.
Always back up if you can.
Double-check you’ve got the right PIT. Wrong one = more work for you later.
✅ End Result: Phone came back to life, no EFS errors, factory reset worked fine, and the customer was happy
